PREVIEW: CW's Friday Night Soaps NIKITA & SUPERNATURAL

Alex’s mission to take down Gogol comes to a head as she infiltrates her childhood home and faces ghosts from her past.

On a completely separate mission, Nikita also ends up at the mansion to steal Semak’s (guest star Peter J. Lucas) black box. Nikita and Alex run into each other and decide to join forces, but they run into a major roadblock.

Meanwhile, Michael and Owen (guest star Devon Sawa) work together to figure out Percy’s secret plan with the Guardians.

Aaron Stanford and Melinda Clarke also star. Deran Sarafian directed the episode written by Kristen Reidel.

SUPERNATURAL follows a new episode at 9:00 p.m., "Adventures in Babysitting."

Still reeling after what happened to Bobby, Dean becomes dangerously obsessed over finding a way to take down Dick Roman (guest star James Patrick Stuart).

Meanwhile, Sam decides to help a teenage girl (guest star Madison Mclaughlin) look for her father (guest star Ian Tracey), a hunter who has gone missing. Sam traces his last steps to a truck stop where the help (guest star Meghan Ory) turns out not to be so friendly.
